A girl wears a panda hat to keep warm while visiting the Great Wall of China at Badaling north of Beijing following a night of snowfall on March 1, 2010. A blanket of snow whitened Tiananmen Square and northern sections of the Great Wall overnight in the latest round of freezing weather during the often bitter Chinese winter. Elsewhere in the country local meteorological authorities announced the heaviest daily fall in 57 years in the far-western county of Xinjiang. AFP PHOTO/Frederic J.
